The configs look okay, right? I’ve got a keychain mentioning a password of BEEFBOY (a highly secure password that is practically invulnerable to even the most sophisticated dictionary attacks), starting way in the past, lasting forever. I haven’t shown the EIGRP config, but that’s all okay – the AS numbers match and the interfaces are activated.

I was a little new to keychain logic at the time, and I wasn’t entire sure how to troubeshoot. So, I tried some EIGRP debugging:

Wait a second – why is there a space on Router 2’s key, between the key itself and the closing quotation mark?

It turns out that somehow I’d typed an extra space when I put in the password!

But what’s truly frustrating is the fact that if you copy and paste the config into a text editor, the space isn’t there!! Another high-quality design choice by the makers of everyone’s favourite router operating system. Anyway, I fixed the password, and it was all good.

The show key chain command. A nice, quick, simple way to make sure your keys are all in order, even when your configuration has your convinced that everything is fine. Thank you, Cisco, for this truly glorious and magical command.

Hi!

I’m Chris, a network engineer from London. This is a blog of random knowledge I’ve acquired while studying for some sweet sexy network engineering certifications. Technically vendor neutral, but as you’ll soon find out, I love Junos very much.

As I learn cool new stuff, I try to write it up with plenty of jokes, and a generous dollop of silliness, so that you’ll have as much fun learning about networking as I do.
